This invention relates to economizers for use with furnaces and moreparticularly to an improvement of the economizcr shown in my co-pendingapplication, Serial lilo. 263,864,

filed March 22, 1928, for economizers for use in conjunction withfurnaces.

An important object of the present invention is to so improve thestructure of the water tube element of the economizer as to avoid thenecessity for employing loose baffles or applied baffles thereto.

A further and more specific object of the invention is to provideradiation or water tube sections for use in such structures having ribswhich, when a plurality of the sections are combined, unite to form abaiile for directing the heating gases of the economizer downwardlyabout the lower portions of the sections.

These and other objects I attain by the construction shown in theaccompanying drawings, wherein for the purpose of illustration is showna preferred embodiment of my invention and wherein Figure 1 is avertical sectional view through an economizer constructed in accordancewith .my invention;

Figure 2 is a sectional view taken on a plane extending vertically andcentrally through the upper portion of the economizer, the plane of thesection being indicated by the line 2--2 of Figure 8.

Figure 3 is a section on the line 3-3 of Figure 2, and

Figure 4- is a perspective view on a reduced scale of one of thesections of the radiator.

Referring now more particularly to the drawing, the numeral 10generally-designates a substantially rectangular casing, opposed wallsof which are provided with an inlet 11 and an outlet 12. The casing ispreferably supported from adjustable legs 13 permitting ready alignmentthereof with a flue pipe, conducting furnace'gases from the furnace tothe chimney. The walls of the casing are provided with wash andextension openings 1% having removable plugs 15 permitting access to theinterior of the casing.

.Disposed within this casing is a radiator the ordinary sectionalcolumnar radiator.

These nipples, as well known to those'familiar with the art, projectoutwardly from the side faces of the radiator for a short distance. Theradiator has connected thereto pipes 16 and 16*, the pipe 16 serving toconvey water to the radiator and the pipe 16 serving to convey waterfrom the radiator.

In accordance with my invention, I provide the radiator with columns,preferably of an unequal number, and form upon opposite side faces ofthe radiator sections ribs 20 aligning with the nipple openings of theupper header and projecting outwardly from the outer faces of thesection a distance equal to the depth of the bosses. This rib extendsover the top of the upper header, as indicated at 21, and extendsdownwardly for approximately one-half of the length of the section ateach face of the radiator.

It will be obvious that when the sections 16 are secured together in theusual manner, adjacent faces of the ribs of adjacent sections will comeinto engagement with one another, so that these ribs combine to produce,between the sections, baffle walls, which extend approximately forone-half of the length of the sections.

The ribs of the outer faces of the outermost sections extend forengagement with the walls of the casing to seal thereagainst, and theribs upon the upper ends of the headers combine to form a baflle abovethe radiator which engages the top wall of the casing and effects a sealtherewith. This battle, in the applied position of the radiator, liesdirectly between the inlet and outlet, so that gases entering the inletmust pass downwardly therebeneath as they move to the outlet.

Since the construction hereinbefore set forth is capable of a certainrange of change and modification without materially departing from thespirit of the invention, I do not limit myself to such specificstructure except as hereinafter claimed.

I claim 1. In an economizer, a casing, a sectional radiator within thecasing, each section of the radiator having upon its side faces and atits upper end a'rib structure, the rib structures of the sectionscombining in the assembled relation of the sections to form bafflesbetween adjacent sections of the radiator, the ribs at the upper ends ofthe sections engaging the up er Wall of the casing, the ribs of theouter aces of the outermost sections engaging opposite end wallsthereof.

2. In an economizer, a casing, a sectional radiator therein, thesections of the radiator having centrally disposed means at the upperends thereof which form battles and which combine in the assembledrelation of the sections to divide the space between the sections and todivide the space between the sections and the upper wall and upperportions of the side walls of the casing.

3. In an economizer, a casing, a sectional radiator therein, thesections of the radiator having centrally disposed means at the upperends thereof which form baflies and which combine in the assembledrelation of the sections to divide the space between the sections and todivide the space between the sections and the upper wall and upperportions of the side Walls of the casing, the casing having an inlet andan outlet aligning with the upper portion of the radiator.

In testimony whereof I hereunto aflix my signature.

JOSEPH G. STROCK.
